Question: 1. Write an O(m) algorithm to find in a digraph either a directed circuit or a topological sort. Hint: Show that 1) each acyclic graph

1. Write an O(m) algorithm to find in a digraph either a directed circuit or a topological sort. Hint: Show that 1) each acyclic graph has a candidate for v1, i.e, a node v such that there is no (u.y) EA; 2) Glv is acyclic. We can repeat this argument. Show that the run time is O(m)
